1 u all whom it mag/concern:

Beit known that 1, Brass W. Kannma citizen of the United States, residinin the county of Roanoke and State of 1r inia, have invented certain newand usefu Improvements in Car-Truck Brakes, of which 7 the following isa specification.

invention relates to car truck brakes and 1s a. continuation in gart ofm previous application for U. Lette'rs atent formation of parts and intheir combination and arrangement, all as shown in the.

preferred embodiment de noted in the drawm s and .as described erein andfinally pointed out in the claims.

In. the drawings, Figure 1 is a broken plan view of a car truck, havingthe features of-my invention applied thereto and Fig. '2 is a sideelevational view of the same. Fig. 3 is 'atransverse vertical sectiontaken approximately on. the line 3-3 of Fig. 1

and showing also the draft sills of the car body. Fi 4 is a similar viewtaken apalso showin the draft sills. Figs. 5 and 6 are'detache verticalsectional views taken a proximately on thelines5-i and 6 6 o Fig. 1'respectively. Fig. 7 1s a (partial transverse vertical section corresponmg in art with Fig. 3 and showin ori'n' of the brake hanger brac cetconstruction. )Fig. 8 is a partial side elevational view. showing theform of bracket disclosed these hangers 29 with "brackets 31 extendinginward from the side 100 frames. These-are preferably carried on a crossbar 3'2or '33 which extends across the "truck from frame to framebeneath the bolster and beneath the brakes, although as shown in Figs. 7and 8 they may-be cast out 105 in Fig..7.-

In these. drawings .there 1s depicted a type,:.with window openings 6and 7 and upper and lower arch members 8 and 9 are provided along eachside of. the truck, the same being supported upon theoil boxes 3. Abolster-10' as arms extending through is carried on the springs 11 beingbottom arch member9, the

The load of the interposed therebetween.

on "the line 4-4: of Fig. '1 and a modified car is received on a centerplate 12 on the bolster and the bolster is provided with transversemembers 13 which are dropped down at their centers to pass under the carbod draft sills 14, the ends of these cross bolsters being somewhathigher than their central portions to provide space for the truck brakehanger brackets.

For braking the truck there are provided threebrake beams 15, 16 and 17,each with the customary brake heads and shoes for contact with thewheels. There is provided a lever for each beam, these being desig nated18, 19 and 20 respectively and to then. their respective beams arepivoted between the extremities of the levers; There is then provided anequalizing lever 21, the same having a pivot point 22 between itsextremities. A leveractuating member 23 extendsfrom one extremity of thelever 21 to the one extremity of the lever 19 and a secondlever-actuating member 24 extending between the :other extremity of thelever 21 and one extremity of the lever 20. A third lever-actuatingmember 25 extends from the other extremity of the lever 19 to the oneextremity of the lever 18. the other extremities of the levers 18 and 20being provided with pivot points. As is usual in such brake leversystems, the brake levers may be actuated from any of the fixed pivotpoints, the others being fulcrumed, and in the embodiment shown inthedrawings the pivot extremities of the levers 18 and2-O are providedwith fulcrums 26 and, 27 respectively, the lever-actuatingmember 28being connected to the pivot point 22 of the lever 21. Thus a pull onthe rod 28 will actuate the-entire svstcn'l of levers and set all of thebrakes, drawing the beams with heads and shoes up against the wheels,the hangers 29 swinging around the pins 30 to allow this.

Theibeams are supported by means of suitable hanger as "integsral numera3 hating the and 38 in however, they should not .be connected 110 acrossthe frames by any rigid or integral tie. These hanger brackets extendfrom the one arch member inwardly toward the center of the truck and incases when the cross bar is used the bar extends inwardly and on acrossthe truck to the bracket on the opposite side. From the horizontalbranch a vertical stem 38 rises away from the rail, and from the upperextremity of this stem one or more substantially horizontal arms 34extend outward above the brake beams and terminate in the bosses 35 toreceive the hanger pins 30. Thus there-is provided a space adjacent thevertical stem of the bracket for the truck springs and the bracket islocated in the space rovided for it beneath the upwardly inclinedbolster end. Where two branches occur these extend in oppositedirections lon truck and the opposite rake hanger reactions in a measurecounteract each other.

In cases where the cross bars 32 and 33 are used it is preferable thatthey be not rigidly secured to the frames as by riveting or casting. Forthere is a tendency for the opposite frames to move relative to eachother and it is not. desirable to construct this bar or cross member toresist this movement and set up undue side forces in the frames. Hencewhen the brackets 31 are connected together across the truck, Ipreferably provide open-side pockets 36 in the side frames, these thecross bars and restrain them a ainst material movement either axially othe bars or longitudinally of the truck or vertically. ,In assembling,the side frames are simply slipped on the ends of the bars at the sametime the frames are placed on the bolster arms and the keepers 37 of thebolster arms prevent the frames from spreading.

The cross bar 33 is also formed with openings or other means to supportand guide the brake-actuating members 23, 24: and :28, the member 23 inthe present embodiment being extended to engagean openin in this bar.The cross bar 32 also provi es a desirable point for the location of thefulcrum 26 for the pivot end of the lever 18. When the cross bar isprovided for my hanger brackets as shown the side frames are relieved ofall torsional-strains from the brake hanger loads or from the load ofthe fulcrum 26. The-cross bar 32 is preferably formed of a commercialI-beam with the web horizontal and with the brake hanger bracket 31riveted to the web and extending 1 with the end of the I-heam into thepocket of theside frame near its lower edge.

Tlte 'ltulcrnm bar 27 is secured to any eonvenientipart of the truckstructure such as onenof the cross members 13, as shown in.

therdraawings- My brake mechanism thus described em bodies impiovementsthe merits of which 'tudinally of the eing formed to receive the endsof.
